— The sodium salt-assisted low temperature activation of bentonite (BB) was attempted. The unique features of the raw bentonite and BB were characterized with respect to the morphological,...

 — Hydrochloric acid (HCl) was used as an acid activating agent for the natural bentonite. Sodium hydroxide (NaOH), hydrogen peroxide 30% w/w (H 2 O 2), sodium chloride (NaCl), sodium acetate (Na-Ac), and acetic acid (Ac-Ac) were of analytical grade (Sigma-Aldrich) and used without further treatment.

 — Bentonite is processed to give sodium and calcium. montmorillonite, activated clays and organo-clays all of. which have different properties that can be applied in.

 — 13 Citations. Metrics. Herein, the facile one step acid activation of bentonite derived functionalized adsorbent (AB) for the effective remediation of both ionic and non-ionic secondary...

The sodium activation involved addition of 2–2.5 wt.% Na 2 CO 3 to Ca-rich bentonite in diluted aqueous slurry, followed by washing and drying. Later the process was modified to avoid the costly and time-consuming drying step.

 — The present investigation utilized activated sodium bentonite clay as an adsorbent agent to facilitate the elimination of Cr (VI). The clay was subjected to acidification and thermal modification techniques to enhance its adsorption capacity.

 — Sodium activation, which is an example of chemical modification, is a process developed in the 1930s [5,6]. The discovery was prompted by the observation that only bentonites rich in Na-smectites were suitable for the use as binders in foundry moulding sands, while bentonites containing Ca-smectites proved inadequate for this …

 — The activated bentonite was testing using standard testing procedures for drilling fluids and cementing such as rheology, fluid loss control, settling, compressive strength and thickening time...

 — This study explores, as an alternative to sodium bentonite, the possibility of (Na, Ca)-bentonites to meet the required drilling mud properties. Activation of the bentonites was performed using the most popular (Na 2 CO 3 ) and also the most controversial additive (MgO) and their blends.

 — In this study, the organic modification of montmorillonite in calcium bentonite (SN) was performed by poly(acrylic acid) (PAA) and its sodium salt (PAA/Na). Additionally, for the purpose of comparison, the sodium-activated bentonite/poly(acrylic acid) (SN-Na/PAA) composites were also prepared.
